SPECIFICATION forming part of Letters Patent No. 431,970, dated July 8,1890. Application filed February 27, 1889. Serial No, 301,326. (Il'omodel.)

To alZ whom it may concern:

Be it known that I, JAMES A. GRAHAM, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofVisconsin, have invented certain new and useful Improvements inHarvester-Reel Sup portsyaud I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

Myinvention relates to an improvement inharvester-reel supports; and theobjects of my invention are, first, to provide for the adjustment of anadjunctive part of a harvester or similar machine, a lever with alocking de vice, the latter arranged to be operated by an axial movementof said lever and to make a support for harvester-reels with connectedparts, by means of which the driver from his seat may easily adjust itto suit the condition of the grain; second, to provide a reel-support inwhich the weight of the reel is balanced by a spring when being adjustedupward and downward, and, third, to furnish improved devices forcontrolling the support and adjustments of the reel, as hereinaftershown. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation of thereel-support, part being broken away. Fig. 2 is a rear elevation. Fig. 3is a section on line y y, Fig.1. Fig. 4 is a section 011 line 00, Fig.1, looking downward. Fig. 5 is a plan view of the reel-support, certainparts being omitted the better to show others. Fig. 6 is a verticalsection of the parts shown in Fig. 5 on the line y y, omittingplunger-pins and fingers it.

In the drawings, A is apart of the harvestcr-frame on which is fastenedthe base-support piece B. The upright arm 0 is pivoted to the base-pieceB on rod 0, and some distance rearward and at a greater height thebrace-arm D is pivoted to the same piece at d. The upper end of arm 0 ispivoted on rod 6' to the coupling E, and the upper end of brace D is inlike manner connected with coupling E at 6 The reel-bearing arm F ishinged upon rod 6' to arm 0 and coupling E. The hand-lever H is pivotedupon inwardlyprojeeting bosses e c on coupling E. The reel L is held ina sleeve formed on the forward end of arm F, and is of such form ofconstruction and driven in such manner as may be desired. The brace Dterminates at its upper end in the sector-D concentric with pivot 6 Thissector has at suitable intervals holes to receive the end of plunger-pinI Arm F has upon its forward end the reelbearing sleeve L, and upon itsrearward end 011 the side opposite to sector D when placed in positionthe sector F concentric with rod 6. In this sector are holes to receivethe plunger-pin I. These sectors both traverse the center of the hingeof lever H, (see Fig. 1, full and dotted lines,) and hence can always bebrought into engagementwith the plum gerpins 1 I which are placed in theline of such center, Figs. 3 and 4.

The coupling-piece E is preferably made in two parts, divided on themedian line and held together by a bolt at 6. Its upper sides are bentoutward, so that lever H is pivoted.

on bosses e e on its inner surfaces. These bosses are hollow and providebearings for the ends of the plunger-pins I 1 The forward end ofhand-lever H is connected to arm F by the rod h. I prefer to make thehandlever of a cast part, which furnishes a support for the plunger-pinsI I and has an extension reaching to the driver, consisting of a hollowpipe H, on which is the rod H on the rear end of which is the handle Hand on its forward end are fastened the cam-like fingers h 71/ by pin7L2, inserted through holes 71 of handle, which operate the plunger-pinsI I by turning handle H When used in this description to indicate thegeneral operation of the lever, the parts just described will be calledthe hand-lever. This construction of the hand-lever gives strength withlightness and provides a good bearing for the plunger-pins I 1 as alsofor their operating-rod H Figs. 1, 3, and 4. The locking device of thisreel-support consists of the plunger-pins I 1 held in the handle H andin the bosses c c of coupling E and the sectors D F, Figs. 3 and 4-. Theplunger-pins IOC I 1 are made with a projecting lug on each side,(marked, respectively, 0." i for plungerpin 1 and i i for plunger-pin 1and are formed with a recess, in which is placed a coiled spring to holdthe pins in their sectors. The plungers reach past each other and-havetheir lugs at their inner ends, and the operating cam-fingers h h enterbetween the said lugs and operate to withdraw the pins from engagementwith the sectors when handle H is turned. These operating-lugs move inthe guide-grooves G G in handle H, Fig. 4. Arm F, one side of which isshown broken away in Fig. l, is preferably made hollow to provide aconvenient case for the coiled open spring K. Against the rear end ofthis spring is the flange of cup K which receives the forward end of rodK, the rear end of which connects with coupling E at 70, Fig. 1. Thecurved-line guide S is conveniently attached to arm 0 and rod 6', asshown, Fig. 2, and operates to keep the lines out of contact with thedriving mechanism and reel.

The operation of my reel-support is as fol-- lows: WVhen handle 1-1 isturned in the direction of the arrow 7?, the plunger-pin I is withdrawnfrom the sector F, and the reel can be raised or lowered, as desired, bythe lever H acting on arm F through the bent rod it. While thisadjustment is being made plunger-pin 1 holds coupling-piece E rigid witharm 0 and brace D. By reference to Fig. 1 it will be seen that thereel-arm F cannot be lowered without compressing spring K, and hence issupported on said spring while being adjusted up and down, relieving theoperator from holding the weight of the reel by the hand-lever whilemaking such adj ustment. The location of the point of connection betweenspring K or red K and piece E at is, below and somewhat in advance ofhinge e, compensates in partto give the spring a uniform resistance tothe weight of the reel. Then the handle is turned in the oppositedirection, plunger-pin I is driven into one of the holes in sector F bythe coiled spring '1; and plunger-pin l is withdrawn from sector D, andthe reel is moved foward and backward by the handle H on the line W,Fig. l. The stopf on sector F limits the forward movement of thereel-support by contact with stop f on coupling E, Figs. 2 and 5. Bycomparing this line WV with line W the advantages of the action of thebrace D and coupling E will be understood. Vhen pin I is withdrawn fromsector D, coupling E is held rigid with arm F by pin 1 in sector F, sothat they operate as one piece, and the brace'D, being shorter than arm0, and both being hinged to piece E, will relatively depress the rearend of said coupling-piece, and hence raise the forward end and with itsupporting-arm F and the reel. The principal weight to be supported inthis system is the reel, and such an arrangement and propertioning ofthe parts as gives it a horizontal movement would keep it in equilibriumin its forward and backward movements, were it not for thereel-supporting mechanism. To counteract the tendency of this mechanismto overturn or fall down, the members of the support are so proportionedthat the reel in moving either forward or backward from its position ofrest shall describe a line slightly curved upward, just sufficient toovercome the weight of the support, and the reel is thereby movedforward and backward in equilibrium, and will stop in any positionwithout locking and without tendency to fall downward.

The dotted line WV indicates the line of movement of the reel-center inits forward and backward adjustment, which, it is observed, is nearlyhorizontal. Line \V is a true circle struck from the pivot 0, upon whichthe upright arm 0 vibrates through the center of the reel, and indicatesthe line of movement of a reel supported upon a single pivot. Line Z isstruck from the pivot c of arm 0 through the hinge-pivot e, whichconnects arm 0 with piece E, and is a true circle from said center. LineZ is struck from the pivot d of brace D, upon which it is connected tothe base-piece B through hinge 6 which connects said brace with couplingE.

By comparing the line Z, representing the line of movement of theforward end of the coupling-piece E, with line Z, representing themovement of the rearward end of the same piece, it is seen that theforward end of piece E is relatively raised in adjusting the reelforward, and that the line XV, described by the reel in its forward andbackward movement, is practically horizontal, inclining slightly upwardin each direction from the central position, and hence that in theforward and backward adjustment of the reel it is practically balancedwithout regard to the spring K, which does not act at all in suchadjustments. This balancing of the reel in its forward and backwardadjustment is effected by properly proportioning the relative length ofthe supporting arm 0 and that of brace D, as also in the due placing ofthe positions of their pivotal connections with the base 13 andhinge-connection with coupling E. It is thus seen that all theadjustments of the reel are controlled by a single lever, which is shortand easily kept in reach of the driver, and that it is balanced in itsforward and backward adjustments by making its supporting parts ofproper proportions, and that it is balanced in its vertical movement bythe interposed spring K.

Various modifications can be made in these devices without departingfrom the scope of my invention.
